+Message-Id: <20120314032729.ga16...@yabbi.bne.redhat.com>

+Cc: Thomas =?iso-8859-1?Q?B=E4chler?= <tho...@archlinux.org>
+
+Introduced in 26831a6eeac6762ad4d99532f62ebbab0827de10.
+In said commit, the old-style button events were changed to delta
+accumulation. Alas, for circular scrolling, a positive delta is up whereas
+for everything else a positive delta is down.
